When I do as your example in README.md,I got the error as below:

2018/04/24 19:57:26 [error] 125048#124724: *47909566 lua entry thread aborted: runtime error: ...y_For_Windows_1.13.5.1001_64Bit\x64\nginx//resty\rsa.lua:149: cannot resolve symbol 'RSA_new': 找不到指定的程序。

OpenSSL symbols are not exported by default in the Windows.
I don't have a Windows environment to test, but you may solve this problem by adding these lines under local C = ffi.C:

-- you need to have ssleay.dll in your system library path
if ffi.os == 'Windows' then
    C = ffi.load("ssleay.dll")
end

Another solution is to use gcc from msys2 to build your OpenResty suite, including the OpenSSL library.
gcc will export all symbols by default unless -fvisibility=hidden is specified. I guess its behavior is consistent under Windows.

@spacewander My Openresty_For_Windows 64bit is work well, and some other third librarys works fine when I put them under nginx\resty, can you please describe it in detail how shoud I do?
Also, can you make the rsa library compatible with Openresty_For_Windows?If need I can post request under Pull requests.

@sstong123
The problem is that I don't have a Windows to test for. BTW, will you try the official windows release? https://github.com/openresty/openresty/blob/master/doc/README-windows.md
